Hidden Mickey Cards???

[mamacandy3]

I have seen a couple of people refer to Hidden Mickey Cards? Can someone explain it to me or possibly have a pic? We are leaving for the Wonder in 11 days! I can't wait! I am trying to do everything possible for this cruise! I think I am equally excited as my kids! Thanks for anyone who can help!

I think you can go to Guest Services and ask for a list of Hidden Mickeys onboard. Is that what the people are referring to?
